Improvement in reservoir cooking-stoves



UNITED STATES PATENT OEEIo SIMON w. FRANCE, OF BROOKLYN, N W YORK.

IMPROVEMENT IN RESERVOIR COOKlNG-STOVES.

Specification forming part of Letters Patent No. 137,355, dated April 1, 1873; application filed i September 7,1872.

To all whom it may concern:

Be it known that I, SIMON W. FRANCE, of the city of Brooklyn, county of Kings, in the State of New York, now temporarily residing at Hamilton, Province of Ontario, Canada, have invented an Improved Boiler Attachment for Cooking-Stoves, of which the following is a specification:

My invention relates to certain improvements in boiler attachments to cooking-stoves, by means of which the water in the boiler may be quickly raised to the boiling-point, or may be kept at a moderate or very low temperature, as desired, by simply turning certain dampers herein described and also to an improvement by means of which the steam generated in the boiler is conducted off through the smoke flue without escaping into the room.

In the annexed drawing, Figure l is a vertical cross-section of a boiler with the extension attachment on which it rests, and the fines or pipes attached thereto. Fig. 2 is a top view of a cooking-stove with the extension for supporting a stationary boiler or reservoir on a reduced scale. Fig. 3 is a top view of said extension attachment, showing the partitions and dampers to direct the course of the heated air after leaving the stove.

A, Fig. 1, is the boiler, and B a smoke and hot-air flue through the center of it. This flue has a number of cross-tubes, G 0, extending from side to side, open at both ends, and attached to the pipe B by water-tight joints, so that the water in the boiler will flow through said cross-tubes without escaping into theflue. D is the bottom of the extension attachment, on which the boiler rests, a dotted line, D, showing the main bottom thereof, while E shows a flue or channel projecting below said main bottom and extending across the extension attachment. This flue or channel is open at the top, and is of the width shown in Fig. 3, and of the depth shown in Fig. 1. I I are the top and back-end plates of the stove. L L are braces or lugs on the extension attachment for fastening it to the stove. P is the opening in the top of the stove, through which ing up to and connecting with the chimney S above the boiler, to conduct off the smoke and heated air when not allowed to pass off directly through the flue B. That part of the channel .E which projects beyond the back part of the extension attachment is of course closed on all sides except the opening Q. F is a damper, which fills the channel E when. turned down; and M M, Fig. 3, are partitions or deflectors to compel the smoke and heated air in that case to pass around under the bottom of the boiler in the direction shown by the arrows. This damper has lips on each side to prevent the smoke and heated air from passing around said partitions when it is turned up. G is another damper, which also fills the channel E when turned down, and closes the flue B when turned up to a horizontal position. N N are partitions, which continue the sides of channel E up to the bottom of the boiler from the damper Gr back. 0 and O are the handles by which the dampers F and G are operated. The extension attachment is made of cast-iron, and has a flange around its upper products of combustion will pass around the partitions M M, under the bottom of the boiler, and up through the flue B, and through the interstices between the cross-tubes O G, heating the water in the boiler to'the boiling-point in a short time. When the damper Gis turned up and the damper F down, the heated prodnets of combustion will pass around the partitions M M under the bottom of the boiler, as before; but will pass off through the pipe H, thus keeping up a moderate degree of heat in the boiler. But when both dampers are turned up the heated products of combustion will pass off directly through the channel E and deflectors M M under the bottom of the boiler, and out under damper Gr through the pipe H to the chimney.

J is a steam-pipe leading from the top of the boiler into the flue B, and K is a valve in said pipe so balanced that when the water begins to boil and generate steam the pressure of the steam will raise the valve and pass off into chimney without escaping into the room. The valve should be so balanced that the pressure of the steam will raise it before it will raise the lids of the boiler, and will close automatically when the steam goes down. There may be, however, a wire arranged in the pipe to keep the valve open when desired, but the water will boil sooner if the valve is closed.

It will be seen that this extension attachment can easily be applied to any ordinary cooking-stove.

What I claim as my invention, and desireto secure by Letters Patent, is

1. The extension attachment to a cooking stove for supporting a boiler or hot-water reservoir, provided with the channel E, dampers F and G, and escape-flue H, all constructed, combined, and arranged to operate substantially as described.

2. In combination with said channel E, dampers F and G, and escape-flue H, the partitions or deflectors M M, as and for the purpose set forth.

3- In a boiler or hot-water reservoir for a cooking-stove, the combination of the smokeflue B with transverse water-tubes O passing through the boiler or reservoir and the side smoke-flue H, with dampers so arranged that the smoke and heated products of combustion may be made to pass 011 through either of said smoke-Hues by turning the dampers, substantially as described.
